max_seq_length=1024,
dtype=None, # Auto-detect
load_in_4bit=False, # Set True for 4-bit quantization
)
# Prepare for inference
FastLanguageModel.for_inference(model)
# Chat template
messages = [
{"role": "system", "content": "You are Granite, a helpful AI assistant."},
{"role": "user", "content": "I need help choosing a laptop for programming."}
]
inputs = tokenizer.apply_chat_template(
messages,
tokenize=True,
add_generation_prompt=True,
return_tensors="pt"
).to("cuda")
# Generate response
outputs = model.generate(

π Evaluation Results
The model demonstrates strong performance on customer support tasks:
- β High accuracy on domain-specific Q&A
- β Coherent multi-turn dialog generation
- β Contextually appropriate product recommendations
Note: Formal benchmark scores are pending comprehensive evaluation.
π¬ Chat Format
The model uses Granite 4.0's chat template:
<|start_of_role|>system<|end_of_role|>Knowledge Cutoff Date: April 2024. Today's Date: [Current Date]. You are Granite, developed by IBM. You are a helpful AI assistant.<|end_of_text|>
<|start_of_role|>user<|end_of_role|>[User message]<|end_of_text|>
<|start_of_role|>assistant<|end_of_role|>[Assistant response]<|end_of_text|>
The tokenizer's apply_chat_template() method handles formatting automatically.
β οΈ Limitations and Biases
π Known Limitations
- π― Domain Specificity: Optimized for customer support; may underperform on general-purpose tasks
- π Knowledge Cutoff: Training data only includes information up to April 2024
- π» Hardware Requirements: Requires minimum 8-12GB VRAM for inference (16-bit) or 4-6GB (4-bit)
- π Context Length: Limited to 1024 tokens; longer conversations may lose early context
- π Language: English only; limited multilingual capabilities
βοΈ Potential Biases
- β οΈ Training data may contain inherent biases from the support bot domain
- β οΈ Recommendations may reflect patterns in training data that could favor certain products/solutions
- β οΈ Users should implement appropriate safeguards for production deployment
π‘οΈ Ethical Considerations
- ποΈ Transparency: Always disclose AI-generated responses to end users
- π€ Human Oversight: Implement human-in-the-loop for critical decisions
- π Data Privacy: Ensure user data handling complies with applicable regulations (GDPR, CCPA, etc.)
- π« Misuse Prevention: Do not use for generating misleading, harmful, or deceptive content
- βοΈ Bias Monitoring: Regularly audit outputs for fairness and bias
π Deployment Recommendations
π» Hardware Requirements
| Configuration | VRAM | Use Case |
|---|---|---|
| 16-bit | 12-16GB | Development, high-quality inference |
| 8-bit | 6-8GB | Production deployment |
| 4-bit | 4-6GB | Edge devices, cost-optimized deployment |
